It has been more than 30 years since the Bosniak clas- sification of cystic renal masses was first proposed (1). This CT-based classification was introduced in 1986 and originally divided cystic renal masses into one of four

Bosniak was the normal radiological assessment procedure for cystic renal lesions. Originally, it relied on computed tomography (CT) scan results and subsequently extended to magnetic resonance imaging (MRI). Renal cell carcinoma (RCC) surveillance was not enhanced in the past 20 years. Bosniak classifications depend on different morphological modifications in renal cysts such as septa

Tabell 3 Bosniaks klassifikation av njurcystor baserad på DT-fynd, med förslag till handläggning (Schoots et al., 2017). Klassifikation: Behandling/Uppföljning: Bosniak I: Unilokulär tunnväggig: Ingen ytterligare kontroll: Bosniak II: Septa eller förkalkning: Kontroll om 6 månader, om oförändrad – ej ytterligare kontroll: Bosniak III: Septa och förkalkning el. endast väggförtjockning: Öppen biopsi/njurresektion och snabbfix: Bosniak IV The Bosniak classification categorizes renal cysts into five groups. Category I. Benign simple cyst with thin wall without septa, calcifications, or solid components, and has a density of 0–20 Hounsfield units (HU) (about equal to that of water). In such cases, a CT scan without intravenous contrast is enough for classification. Using Bosniak classification version 2019, cystic renal masses were classified into 12 category I, 19 category II, 13 category IIF, four category III, and 20 category IV by CT and eight category I, 15 category II, 23 category IIF, nine category III, and 13 category IV by MRI. The Bosniak Classification is used to quantify the risk of malignancy and need for observation or radical treatment based on the findings of computed tomography (CT).

The Bosniak Classification is used to quantify the risk of malignancy and need for observation or radical treatment based on the findings of computed tomography (CT). The case described is that of a 65-year-old man with renal cystic disease who was initially given a Bosniak stage IIF classification and was subsequently managed with CT surveillance.

Bosniak classification system. Background Benign renal cysts are common in the general population and are detected on CT in up to 50% of patients older than 50 years. Most renal cysts represent benign renal cortical lesions and do not require any follow-up imaging. However, as renal cysts become

Regarding the reliability of the Bosniak classification system, several studies have been reported between 1997 and the early 2000s (refer to Sect. 4.3). Among these, one major study by Curry et al. concluded that the Bosniak classification is reliable and requires adequate CT technique.

Bosniak I and II masses are benign and do not require follow-up. Using Bosniak classification version 2019, cystic renal masses were classified into 12 category I, 19 category II, 13 category IIF, four category III, and 20 category IV by CT and eight category I, 15 category II, 23 category IIF, nine category III, and 13 category IV by MRI. The Bosniak classification was originally based on computed tomographic (CT) findings. Magnetic resonance (MR) and contrast-enhanced ultrasonography (CEUS) imaging may demonstrate findings that are not depicted at CT, and there may not always be a clear correlation between the findings at MR and CEUS imaging and those at CT. Bosniak classification version 2019 proposed refinements for cystic renal mass characterization and now formally incorporates MRI, which may improve concordance with CT. OBJECTIVE. The purpose of this study is to compare concordance of CT and MRI in evaluation of cystic renal masses using Bosniak classification version 2019. The Bosniak classification of cystic renal masses (CRMs) has contributed substantially to the stratification of malignancy risk in the 3 decades since it was proposed (1).
